How to Outsmart Reruns and Reairs

I like to record new episdoes of "The Tonight Show." In my area, it airs once at 11:35 p.m. and then week-old episodes air at 2:15 a.m. I am not interested in the week-old episodes, only the ones that air at 11:35. How can I set up Tivo to record the 11:35 and ignore the 2:15? The "record only first run" setting does not help with this issue, and I understand why not -- how can I get around it?

Same deal with other shows that have multiple airings. How can you grab just one of those airings and get Tivo to ignore all the rest that are getting under the radar?
